Sex and Diabetes- Low Libido, No sex life, erectile issues

Hi I’m just curious if anyone has a partner with diabetes in the stage that he takes medication twice a day and has sugar level issues.

Has he had any libido and or erectile dysfunctional and how did you two take care of it ? Does it get worst overtime ? Should he take viagara ?

My SO has diabetes and has little sex drive and at time cannot stay erect. He takes metaformin for his diabetes and sometimes he gets a yeast infection depending on his sugar level. If it’s bad his hands are noticeable trembling. I feel bad for him, he is only 31.

Any help or suggestions is appreciated.
